2.4 trillion won (approx. $1.67 billion). That's the price South Korean businesses paid in 2025 to shield their data from a relentless wave of cyberattacks. As information theft becomes increasingly sophisticated, corporate Korea is treating cybersecurity not just as a checkbox, but as a critical survival strategy.

South Korea Cybersecurity Spending 2025: A 14% Surge

According to data released by the Ministry of Science and ICT on Tuesday, South Korean companies' expenditure on data protection rose 14.3% compared to 2024. This growth brings total spending to 2.4 trillion won, up from 2.1 trillion won last year. The analysis, based on filings from 773 regulated companies, highlights a significant shift in how the private sector prioritizes digital defense.

Financial and Tech Sectors Lead the Charge

Leading the investment are financial and insurance firms, which spent an average of 8.5 billion won per company. Information and telecommunications firms followed closely with an average of 6.2 billion won. The report also noted a jump in specialized personnel; the number of employees dedicated to data protection reached 8,506, a 10.7% increase from the previous year.

The Korean government's disclosure policy, which targets firms with over 300 billion won in annual sales, is successfully encouraging firms to voluntarily bolster their cybersecurity infrastructure.
